Seo Master present to you: The sixth Web E^xponents tech talk features Rob Campbell's presentation on Firebug. Rob works at Mozilla. He's one of the developers that Mozilla dedicated to the Firebug effort last July. Rob is one of the main drivers of the Firebug project, starting and heading up the weekly concalls, and closely tracking bugs and releases. As one of the founders of the Firebug Working Group, I'm excited to see Mozilla taking a more active role in Firebug. The benefits are clear as we see more features and greater stability with each Firebug release. Here's the video of Rob's presentation as well as a link to his slides.



Rob starts by highlighting what's new in Firebug 1.4 alpha. It's a joy for me to see that activation (enabling and disabling) has been simplified. Rob points out that the firebug icon serves also as a menu. One of the menu items is "Open With Editor", which developers will find useful for saving changes to their pages. A much needed UI change is flipping the tabs and buttons. The tabs used to be below the buttons. Putting them at the top is closer to what users expect from working with other tabbed UIs.

The new "pause" button will be useful for anyone debugging JavaScript. This implements "break on next" functionality, making it easier to stop when event handlers are called. Firebug's Net Panel has had significant improvements. The UI is better (colors!), but there's even more. The underlying timing information has been improved to give more accurate results. There are also markers for DOMContentLoaded and OnLoad, to show where those fire in relation to network requests.

Firebug Extensions provide a way for developers to add functionality that can be shared with others. Rob mentions several extensions including:

• Firediff - tracker for changes made to DOM and CSS
• FireCookie - cookie manager
• FirePHP - console logging from PHP
• YSlow - performance tips
• FireRainbow - JavaScript syntax highlighting

Writing an extension is a great way to explore future directions for Firebug.

Rob talks about future roadmap. Firebug 1.5 will focus on extensions - making them easier to build and use. Firebug 1.6 will change the underlying JavaScript debugging mechanism in Firefox to support new features. Add Rob's blog to your RSS reader to find out about these future releases and other improvements to Firebug.

By Robert Do and Dylin Martin, Google I/O Team

In 2011, Google I/O hosted 5,500 developers from 65 countries in San Francisco, but this audience was dwarfed by the more than 1 million developers from 161 countries tuning in via livestream. Next month developers worldwide will come together for three days of coding, sharing and inspiration in this year’s keynotes, sessions and Sandbox demos. And if you’re not joining us in person on June 27-29, this year’s I/O Extended and I/O Live will be even bigger and better, with more I/O Extended locations and more sessions streamed live.

Get together locally: I/O Extended

With I/O Extended, organizers can take the reins and use the momentum behind Google I/O to bring people together. If you’re interested in hosting an event, check out our planning site here. Otherwise, wherever you are, chances are good that there's a community of passionate developers like you already gathering at an I/O Extended event. Find a location near you and RSVP to let us know you’re coming!


Watch sessions live online: I/O Live

Can’t make it to an I/O Extended location? Or feel like staying in with pizza and beer? Bring the party to you with I/O Live, where the keynote and select sessions will be livestreamed on June 27-28. Bookmark developers.google.com/io where we’ll be posting the livestream schedule, as well as the video feed.

This year we’ve doubled the number of sessions that will be streamed, and we will be featuring 4 channels of programming. All sessions, including those not livestreamed, will be recorded and will be available online within 48 hours.

For more info on I/O Extended and I/O Live, keep an eye on the usual places: the Google I/O site, this blog, and +Google Developers.


Robert Do is an Associate Product Marketing Manager on the Developer Marketing Team. He works on helping developers find the tools they need on https://developers.google.com. He also produces hip hop music.

Dylin Martin works with the Developer Marketing and Developer Relations Teams on Google I/O.
